Abstract
Abstract A clamp useful for firmly securing a camper housing within the bed of a pickup truck which allows for efficient attachment or removal of the camper housing. The device includes a U-shaped clamp body having a pivotal connector at one end that is affixed to the camper housing and a reciprocally movable, spring biased arm having a roller at its free end such that the roller engages the lip of the pickup truck bed to permit pivotal movement over center to effect spring locking action of the clamp. The device allows a camper housing to be readily installed or removed from a vehicle bed by manual actuation of the holding clamps.
